All fields give this field is required error

Question

When I submit this form & all fields are correctly populated, the form.is _valid() returns false & all the fields give : this field is required error, even the CharField!!!

can anybody see what's wrong? this is my form:

class TemplateConfiguredForm(forms.Form):
    """This form represents the TemplateConfigured Form"""
    template = forms.ChoiceField(widget=forms.Select(attrs={'id':'TemplateChoice'}))
    logo = forms.ImageField( widget = forms.FileInput(attrs={'id': 'inputLogo'}))
    image = forms.ImageField(widget = forms.FileInput(attrs={'id': 'inputImage'}))
    message = forms.CharField(widget = forms.Textarea(attrs={'id': 'inputText', 'rows':5, 'cols':25}))

    def __init__(self, custom_choices=None, *args, **kwargs):
        super(TemplateConfiguredForm, self).__init__(*args, **kwargs)

        r = requests.get('http://127.0.0.1:8000/sendMails/api/templates/?format=json')
        json = r.json()

        custom_choices=( ( template['url'], template['name']) for template in json)

        if custom_choices:
            self.fields['template'].choices = custom_choices

this my template:

<form id="template_form"  method="post" role="form"  enctype="multipart/form-data" action="{% url 'create_templates' %}" >
 {% csrf_token %}

{{ form.as_p }}

    {% buttons %}
    <input type="submit"  value="Save Template"/>
  {% endbuttons %}



</form>

this is my view:

def create_templates(request):

    if request.method == 'POST':

        form = TemplateConfiguredForm(request.POST, request.FILES)

        if form.is_valid():

            template_configured = TemplateConfigured()
            template_configured.owner = request.user
            template_configured.logo = form.cleaned_data["logo"]
            template_configured.image = form.cleaned_data["image"]
            template_configured.message = form.cleaned_data["message"]

            template = form.cleaned_data['template']

            template = dict(form.fields['template'].choices)[template]

            template_configured.template = Template.objects.get(name = template)

            template_configured.save()
            saved = True


        else:
            print form.errors


    else:
        form = TemplateConfiguredForm()


    return render(request, 'sendMails/createTemplates.html', locals())

The data you pass in your form, here:

form = TemplateConfiguredForm(request.POST, request.FILES)

is captured by the first keyword argument of your signature:

def __init__(self, custom_choices=None, *args, **kwargs):

Remove the custom_choices=None
